Definition: Anthracosilicosis is a rare, long-term lung disorder that can affect millions worldwide. It's caused by a buildup of tiny silicate particles in the lining of the lungs, leading to inflammation and scarring. This condition often occurs in children and adults with a weak immune system, particularly those who are breastfed or who have respiratory infections like pneumonia or bronchiolitis. Treatment depends on factors such as age, severity, and underlying medical conditions.
